Hi Guys, I received my aeroforce scangauge and I went for a little drive... I gunned it and saw up 6 KR at arround 5000 RPM... I did TWO runs 0-150 KM/H, I popped the hood and my manifold was glowing red...

I have a ZZP 3'' DP with a Highflow CAT,Air intake, Autolite 606's, 180 tstat, Borla 2.5'' catback, Stock pulley. and im running 91 octane gaz..

Im looking into headers now,

What could be the problem?
